Question
Three Partners Chandra, Shekhar and Azad invested in the
ratio of 3/2, 2/3, 4/3 in a business. After 3 months Chandra decreased his capital by 50%. If the total profit of Rs. 12690 earned at the end of the year, find what was the Chandra’s Share of profit?Solution
Multiply Ratios by (2,3,3 LCM) i.e., 6x 
Total Capital of Chandra in 1 year = 9x × 3 + 4.5x × 9 = 27x+40.5x = 67.5x Total Capital of Shekhar in 1 year = 4x × 12 = 48x Total Capital of Azad in 1 year = 8x × 12 = 96x 
According to the question 67.5 + 48x + 96x = 12690 211.5x = 12690 x = 12690/211.5 = 60 Hence, Share of Chandra = 67.5 × 60 = 4050
